Inspector Nick Butler said: “We’re urging residents to stay vigilant when answering the door to unknown callers. We’d always recommend using a spyhole or door chain and, if you’re not expecting someone, don’t open the door.

“If you have any suspicions or concerns about someone’s behaviour, always ask to see their ID or call the police on 999, or 101 if they aren’t currently posing a threat to you or anyone else.

“Make sure your front and back doors and windows are locked at all times, even when you’re at home. We’d also urge anyone with elderly neighbours or relatives to pass this information onto them as well, and to keep an eye out for them.

“If you see someone approaching a property and are suspicious about it, please report this to us on 101 and where possible, note any descriptive details.”
